Yes, Tramp’s cryptic is for one with much intelligence (9)
I believe the answer is:
spymaster
'for one with much intelligence' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'yes tramp's cryptic' is the wordplay.
'cryptic' indicates an anagram (a cryptic or obscure order of the letters).
'yes'+'tramps'='yestramps'
'yestramps' anagrammed gives 'SPYMASTER'.
'is' is the link.
Can you help me to learn more?
(Other definitions for spymaster that I've seen before include "M, say" , "Messy part (anag) - M?" , "Secret agent controller" , "Ringleader" , "head of 6?" .)
